    Bilateral Basal Ganglia Lesions Associated with Lactic Acidosis in an End-Stage Renal Failure Patient
    (Turkish Neurological Soc, 2009) Guldiken, Baburhan; Ustundag, Sedat; Yilmaz, Arif; Cakir, Hasan
    Although bilateral basal ganglia lesions are common in hypoxic encephalopathy and methanol intoxication, they are a rare finding in end-stage chronic renal failure. The pathophysiology of both bilateral and selective involvement of the basal ganglia is unclear, but severe metabolic acidosis is one of the affected processes. In this report bilateral basal ganglia lesions and accompanying signs, which ensued after the use of metformin in a patient with chronic renal failure, are discussed.

    (Elsevier Sci Ltd, 2009) Karaduman, Fatih; Asil, Talip; Balci, Kemal; Temizoz, Osman; Unlu, Ercument; Yilmaz, Arif; Utku, Ufuk
    Methanol is a clear, colorless, and highly toxic liquid with a similar smell and taste to ethanol, and is found in many commercial products such as solvents and cleaning fluids. Severe methanol intoxication occurs after suicidal or accidental oral ingestion of solvents. A few patients with methanol intoxication via the transdermal route have been reported. We present a 47-year-old woman with acute transdermal methanol intoxication admitted to the emergency department with weakness, blurred vision, bilateral areactive mydriasis, and deterioration of consciousness.

    (Elsevier, 2011) Asi, Talip; Celik, Yahya; Sut, Necdet; Celik, Aygul Dogan; Balci, Kemal; Yilmaz, Arif; Karaduman, Fatih
    Objective: The aim of this study is to examine the direct medical costs and outcomes of patients with stroke. Material and methods: The records of the patients admitted with ischemic and hemorrhagic stroke to the University of Trakya, School of Medicine, Department of Neurology were reviewed retrospectively in year 2007. Direct medical costs (total costs, radiological, laboratory, medicine, and other) were calculated, additionally cost per life saved and per life-year saved were calculated for stroke patients. Results: The study group consisted of 328 patients (169 male/159 female) and mean age was 66.5 +/- 12.4 years. Length of hospital stay was 10.7 +/- 7.5 days. Mortality rate was 20.4% and the mRS score of the patients was 3.2 +/- 2.1. The average cost of stroke was US$ 1677 +/- 2964(29.9% medicine, 19.9% laboratory, 12.8% neuroimaging, and 38% beds and staff). Cost per life saved and per life-year saved were US$ 2108 and US$ 1070, respectively. Conclusion: This is the first study in order to determine direct medical cost of stroke in Turkey, therefore, it may be guideline for disease-cost management of stroke. (C) 2010 Elsevier B.V.
